Fig. 1. Day length, relative humidity (RH), and temperature (T) from January 2011 to March 2012.MT, Monthly means of daily mean temperature; Tmax and Tmin, Monthly means of daily maximum and minimum temperatures, respectively; T[max] and T[min], Maximum and minimum temperatures in each month, respectively. The hot (grey) and cool (dark grey) seasons are arbitrarily determined based on long-term average recordings of temperature.
